Introduction: This study, conducted between December 2015 and March 2018 at a single university hospital, explored the feasibility and safety of opioid-free anesthesia combined with preoperative thoracic paravertebral block (ThPVB) for patients undergoing elective video-assisted thoracoscopic surgery (VATS). The aim was to assess the impact of this approach on postoperative pain levels and opioid consumption.

Material and methods: Sixty-four patients scheduled for elective VATS were randomly assigned to either the intervention group, receiving opioid-free anesthesia with ThPVB, or the control group, managed with standard general anesthesia. Postoperatively, both groups received oxycodone patient-controlled analgesia along with non-opioid analgesics. Pain intensity was measured using the Numeric Pain Rating Scale (NRS) and Prince Henry Hospital Pain Score (PHHPS). The total dose of postoperative oxycodone and the occurrence of opioid-related adverse events were recorded during the 24-hour follow-up period.

Results: Patients in the intervention group showed significantly lower pain levels at 20 and 24 hours post-procedure ( P = 0.015, P = 0.021, respectively) compared to the control group. Notably, oxycodone consumption at 24 hours was significantly higher in the control group ( p < 0.0001). No serious adverse events were observed during the study period.

Conclusions: This study demonstrates the feasibility and safety of opioid-free anesthesia combined with ThPVB for elective VATS. The approach significantly reduces postoperative pain and the need for opioids, supporting its potential as an effective and balanced perioperative anesthetic strategy.

Introduction: Laryngeal mask airway-blockbuster (LMA-BT) is a relatively new supraglottic airway device (SGAD). In this study, we compared LMA-BT with I-Gel LMA for efficacy of blind tracheal intubation.

Material and methods: We conducted a single-blind prospective study after ethical approval. One hundred American Society of Anesthesiology (ASA) Grade I-III (age 18-60 years) patients scheduled for elective surgery under general anaesthesia with endotracheal intubation were included and randomly divided into 2 groups. Blind tracheal intubation was performed through LMA-BT ( n = 50) and I-Gel ( n = 50) in groups 1 and 2, respectively. The primary aim was to evaluate the first pass success rate of blind tracheal intubation through the LMAs. The secondary objectives noted were attempts and ease of LMA insertion, total time taken for LMA insertion, airway seal pressure of LMA, ease of NGT insertion through LMA, fibre-optic grading of laryngeal view through LMA, overall success rate and time of intubation through LMA, time for LMA removal, and complications, if any.

Results: In the LMA-BT group, the first pass success rate ( P < 0.019) and the overall success rate of intubation ( P < 0.005) were significantly higher than in the I-Gel group. Using LMA-BT also resulted in statistically significant shorter intubation time ( P < 0.0001) with higher airway seal pressure as compared to I-Gel ( P < 0.001). The difference in the first attempt insertion, number of insertion attempts, ease and time of LMA insertion and removal after intubation, and postoperative complications were comparable among the groups.

Conclusions: LMA-BT is a superior device as compared to I-Gel LMA as a conduit for blind tracheal intubation.

Throughout the past decades ultrasonography did not prove to be a procedure of choice if regarded as part of the routine bedside examination. The reason was the assumption defining the lungs and the bone structures as impenetrable by ultrasound. Only during the recent several years has the approach to the use of such tool in clinical daily routines changed dramatically to offer so-called point-of-care ultrasonography (POCUS). Both vertical and horizontal artefacts became valuable sources of information about the patient's clinical condition, assisting therefore the medical practitioner in differential diagnosis and monitoring of the patient. What is important is that the information is delivered in real time, and the procedure itself is non-invasive. The next stage marking the progress made in this area of diagnostic imaging is the development of arti-ficial intelligence (AI) based on machine learning algorithms. This article is intended to present the available, innovative solutions of the ultrasound systems, including Smart B-line technology, to ensure automatic identification process, as well as interpretation of B-lines in the given lung area of the examined patient. The article sums up the state of the art in ultrasound artefacts and AI applied in POCUS.

Introduction: Patients suffering from severe chronic pain often have problems finding an appropriate combination of painkillers. We retrospectively evaluated the effectiveness and safety of pulsed radiofrequency ablation (pRFA) of the genicular nerves in 96 patients with knee osteoarthritis (KO). We hypothesized that age, sex, and body mass index (BMI) may influence the quality of the pRFA treatment.

Material and methods: A diagnostic blockade with total volume of 9 ml of 1% lidocaine (WZF, Poland) combined with 4 mg of dexamethasone with subsequent pRFA with a radio frequency of 300-500 kHz under ultrasound guidance was used during the procedure. The study participants were assessed during regular monthly visits until 12 months.

Results: The nerves' ultrasound identification was successful in 90.62% of the cases. According to the numeric rating scale (NRS), pain was reduced by 50% or more in 64.06% of the cases. The average pain relief period lasted just over 7 and a half months. There were no pRFA-related complications or side effects of the drugs used.

Conclusions: pRFA seems to be safe and effective for the treatment of chronic pain in KO. The outcome of the treatment may be related to the patient's age (block duration increased with patient age) and sex (in women, the therapeutic effect was more effectively prolonged) in our study group. There was also higher effectiveness of pRFA in high-BMI patients, which was close to statistical significance ( P = 0.053).

Introduction: In the era of problems with resistant bacteria strains, pharmacokinetic (PK) modelling offers ways to optimise antibiotic therapy and minimise the risk of resistance development. This bibliometric study aimed to investigate trends in PK modelling stu-dies. The goal was to provide researchers with comprehensive insight and identify future needs.

Material and methods: We used Bibliometrix, VOSviewer, and CiteSpace to analyse Web of Science articles on antibiotic PK modelling from 1983 to March 2023.

Results: We analysed 968 papers following the inclusion criteria and built a keywords co-occurrence map and timeline. The average annual growth rate of subject-related publications was 35.56% between 1983 and 2022, maintaining a continuous upward trend. Roberts J.A., Lipman J., and Wallis S.C. are the three most productive and impactful authors (82, 57, 34 articles, and h-index of 30, 25, 15, respectively). The United States leads in this field of research (29.13% of papers). The most relevant affiliations are the University of Queensland, Royal Brisbane and Women's Hospital, and Monash University. The top three most productive and impactful journals are Antimicrobial Agents and Chemotherapy, Journal of Antimicrobial Chemotherapy, and International Journal of Antimicrobial Agents (181, 83, 47 articles and h-index of 42, 30, 18, respectively). Most articles by keyword clustered on meropenem, vancomycin, and amikacin. Moreover, therapeutic drug monitoring, resistance, antibiotic dosing, target attainment, the intensive care unit, and paediatrics are the most trending aspects.

Conclusions: Given the results of this study, we expect to see a steady increase in interest in exploiting the potential of PK modelling for optimising antibiotic therapy.

Introduction: The main purpose of the study was to assess the impact of preoperative interdisciplinary assessment by the PreScheck Team on optimization of the final selection for elective cardiac surgery.

Material and methods: This is a single-centre prospective observational study. The examined population consisted of 933 adult patients planned for cardiac surgery. After the exclusion of urgent operations, the study group consisted of 288 patients planned for elective cardiac surgery within 3 months from 1.01.2023 with PreScheck assessment (PreScheck Team group 2) and a control group of 311 patients scheduled for elective cardiac surgery between 1.03.2022 and 30.06.2022 (4 months), without preoperative interdiscipli-nary assessment (No PreScheck Team group 2).

Results: Fifty-two patients (18.06%) from the study group were finally excluded from the surgery on the scheduled date. In 46 patients (88.46%) the temporary or permanent exclusion from surgery was a result of PreScheck Team assessment. In the control group 42 patients (13.5%) did not undergo surgery on the scheduled date. Twenty-seven of those patients (8.97%) were permanently excluded from cardiac surgery after admission to the hospital and required additional tests before the final clinical decision, with total hospitalization time of 146 days.

Conclusions: Pre Surgery Check (PreScheck) Team is an original concept that combines classical preoperative assessment and an outpatient prehabilitation clinic. The approach we are proposing here should be a complementary stage in the process of selection for elective cardiac surgery, in addition to the Heart Team recommendation. This two-step decision-making enables real individual risk assessment, selection of the most suitable intervention and better use of medical resources.

The physiological transformations accompanying pregnancy, compounded by the implications of obesity, pose intricate challenges for anaesthesiologists attending to obese parturients. Obesity makes it harder to successfully provide epidural analgesia to a parturient. This narrative review explains the most recent data on the safety and complications of providing labour epidural analgesia in obese expectant mothers. We have emphasised the evidence-based approaches that are the most effective for obese pregnant mothers receiving labour epidural analgesia.
